To expand the expression \((5x^5 - y^2)^2\) and state the answer as a polynomial in standard form, we follow these steps:

  1. Set up the expression for squaring the binomial: \[ (5x^5 - y^2)(5x^5 - y^2) \]

  2. Apply the distributive property (also known as the FOIL method for binomials): \[ = (5x^5)(5x^5) + (5x^5)(-y^2) + (-y^2)(5x^5) + (-y^2)(-y^2) \]

  3. Calculate each term:

    • The first term: \((5x^5)(5x^5) = 25x^{10}\)
    • The second term: \((5x^5)(-y^2) = -5x^5y^2\)
    • The third term: \((-y^2)(5x^5) = -5x^5y^2\)
    • The fourth term: \((-y^2)(-y^2) = y^4\)
  4. Combine the results: \[ 25x^{10} - 5x^5y^2 - 5x^5y^2 + y^4 \]

  5. Simplify by combining like terms: \[ 25x^{10} - 10x^5y^2 + y^4 \]

  6. State the final answer in standard form: \[ \boxed{25x^{10} - 10x^5y^2 + y^4} \]
